Application of the object model in the modelling process of locomotive drive units

The article deals with the problem of selecting the object model of technical solutions to the mechanical part of the locomotive traction drive. The basis of the accepted model is a concept that considers a technical object as a set of internal elements, external elements of the environment, as well as relations between their sets. The proposed model is adapted for use with modern CAD systems. Approbation of the model is carried out on the example of the synthesis of a rational design of the suspension of the locomotive traction drive, reducing the possibility of self-oscillations. As a result of the use of the proposed model, two patentable variants of the suspension of the locomotive traction drive were created, which solve the problem of reducing the likelihood of self-oscillations of the carriage.
